My references here are a combo of the ancient middle eastern Ifrit, the ancient Jewish monster 'Behemoth', and typical Judeo-Christian demons.
Dr. Brice Bannington was unearthing the structures surrounding the Ziggurat of Ur and came across an ancient oil lamp that had been locked away, covered in chains and mystical wards, sealed deep in the earth. The spirit is without an independent physical form, and inhabits Bannington's body in order to become incarnate. Strong emotions, especially rage, allow the beast to emerge, so Bannington must take care never to lose control.
